Silver laced Wyandotte roo?

I got some chicks about 3 weeks ago from the feed store. They're supposed to be all girls but this one is looking more and more roo-ish. What do you all think? I want it to be a pullet because it's the only one that actually LIKES to be held.

Which one do you also think is a boy? One of the pictures has a golden laced Wyandotte and the other has an Americana. They were supposed to be girls with a 95% rate of accurate sexing. I only bought 4 chicks. I would hate to think HALF of them were boys!

The GLW is a Roo too.
There is no doubt for me. Look at the upcoming blush in the comb area. I have some Wyandottes myself and my feelings say it is a cockerel.
